====LIMB Data and Climate Change====
The LIMB sub-daily rainfall data midpoint is 2002, which differs from the ARR baseline period of 1990. Below is a worked example of applying a baseline change in the tool for the <b>Near term</b> and <b>SSP2-4.5</b> scenario. Note, this is not required for daily or longer rainfall durations.

<ol>
<li> Calculate the difference in temperature, comparing the ARR values to the LIMB values:
<ol>
<li> From [https://www.arr-software.org/pdfs/ARR_190514_V4.2.pdf ARR v4.2] Book 1, Chapter 6, Table 1.6.2: Temperature change = <b>1.2</b>
<li> From the LIMB reference document above, Table 3: Temperature change = <b>0.66</b>
<li> Therefore, baseline temperature change = <b>0.54</b>
</ol>
<li> Update the "Baseline Change" value in the climate change dialog within the ARR to TUFLOW tool.<br>
[[File:Climate_change_scenario_dialog_limb_baseline_change.png]]
<li> Run the tool and check that the climate change uplift factors match the values referenced in the [https://data.arr-software.org/static/pdf/LIMB_Addendum_climate_change_considerations.pdf LIMB reference document Appendix A tables].
